In this paper, the author analyzed an applicability of selected types of time-frequency distributions that belong to Cohen’s class and their reassignments for signals similar to those obtained during machinery diagnostics. At the first step of performed studies a synthetic multicomponent signal that contains both stationary and non-stationary components was analyzed using algorithms based on various...
The paper presents the results of computational studies on damage localization in beam-like structures based on an approach of application of selected time-frequency distributions to modal shapes of vibration. The studies were performed on the results of finite element analysis on determination of modal shapes of vibration of a composite beam. The damage detection and localization procedure was shown...
